I am having problems getting my mpeg-2 files (converted to mpeg-4) using the latest version of Xpress and play correctly on my Apple iTouch.

I use the ISO MPEG-4 template and select the output container ipod video (assuming that means itouch video will play or accept that format).

I used iTunes (latest version) to transfer files from my harddrive to the iTouch.

Symptoms range from audio loss (good video and audio for the first 28 minutes of a 30 minute video, but no audio the remaining 2 minutes, only silent video).

This looks like an XPress encoding problem as I can play the mpeg-4 file correctly from my desktop.

I run Windows Vista/64 with 8GB of RAM, and twin 500GB SATA drives. All updates to software and drivers are current.

Wait, so you can play the MPEG-4 file from your desktop with no problems, but playing it through your iTouch, it loses audio in the last 2 minutes?

Or do you mean that the MPEG-2 files are fine, but after you convert them to MPEG-4 with XPress, the problems arise?

Does this happen to all of your MPEG-2 files? Is audio loss the only problem?

I tried converting a DVD compliant MPEG-2 file to MPEG-4 with the ipod video container and my results were fine. What are the specifications of the MPEG-2 file?

Hi all,

I'm currently trying the 4.0 Express - especially to convert h.264 ts files from a satellite receiver. Everything goes fine, but audio AC3 5.1 source file is always converted to a DVD-compliant mpeg file with a 2 channels DD output.
Is it due to the "file processing", as written in the Help, or is there a "trick"?
The answer is capital to pay or not the licence.

Tnans to all!

Has anyone got any suggestions for settings to encode mpeg2 files to H.264 with very little visual loss. I would like to archive files using this format, but can't seem to work out all the settings... any ideas are greatly appreciated

hello there!

i have video source material recorded in transport .m2t files.
my video editing system is avid media composer. unfortunatly avid has no support these files to directly import in aplication. and im using xpress to convert m2t to quicktime mov files. using option without compression full frames. ouput files becomes very large. its more then 10 times increases file sizes. what option i should use to save video quality unchanged and decrease file ouput sizes?

thank you!

I am trying to recode 30 minutes of Full-HD .mts (Panasonic AVCHD - 3.3 GB) as WMV and it takes about 11 hours. :-( Surely this is a little over the top?
I note that .wmv is the only video I can work with on my Intel Core 2 machine with 4 GB of memory. Anything else just judders and jars.
I first used a bitrate of 8000 instead of the default of 1000, but am now trying 4000 deinterlaced. However I can leave my machine on for several weeks if I want to transcode everything. Is there a better way?
(Sorry if this is a dupe, but this forum interface is the least intuitive I have seen in years. I feel like I'm back in the Fidonet era! :-)

It could simply take that long.
I converted a 6 second full HD .m2ts file to WMV (default settings: bitrate of 1000, 1pass CBR) just to see how long it would take. It took 1 min 41 seconds. Doesn't sound long, but for a six second video, that's a long time.
Then again, I'm only on a Pentium4, so that's probably not helping.

Martin,

It is taking exactly as long as it is supposed to. I have a Quad Core for my setup and it takes me anywhere from 5 to 8 hours to convert a movie to VMWHD. The problem isnt their software, but the way Microsoft does their WMV encoding. It is by far the slowest convertor that I have seen these days. I don't know why, it is just like that. So don't feel bad, I have heard of other people needing over 24 hours to do a conversion.

Unfortunately, that's how long it takes. I'm in the process of ripping/converting/upscaling my DVD collection to 1280x720 (720p) using WMV9AP (it has the best output over all other WMV codecs, even WMV9) and it takes 24 hours or so on my Quad Core Q9300 w/ 2GB of RAM .... per DVD.

On my Dual Core E6750 it took just over 48 hours per DVD.

XViD and H.2764 just don't provide the same quality for streaming to my XBox 360 since they are limited to 4GB in size.

I am using TMPGEnc to convert from AVI to MPEG2 so I can build DVDs from these files. For some reason the resulting MPEG2 files are much larger. The AVI files are ~300M and the MPEG2 files are 700M-1GB. Since MPEG2 is compress and lossy I would expect them to be smaller.

I have gone directly from AVI to MPEG2 and am also considering going from AVI->VirtualDub->AviSynth->TMPGEnc->MPEG2.

Thanks in advance!

What are the attributes of the AVI file? Resolution, framerate?

I'm thinking that the only way the DVD-compliant MPEG-2 could be bigger is if the AVI files are worse than DVD quality.

Does 4.0 support blueray mkv encoding to divx or any other format? If so why wont it allow me to import it as a source file. but will allow a 1920x1080 wmv file as a source. The result of this encode is wonderful, but will I only be able to use wmv and not blueray mkv?

Try downloading the latest trial version which was released on June 26. It's supposed to have Blu-ray support.

Whenever i bring 1440x1080 HDV clip to the program it reads it correctly as 16:9. Unfortunately when rendered to QT it creates black bars on top and the bottom so to work around it i force the program it present the clip as 4:3 -- that gets rid of the black bars... But when i bring in loots of clips they all read 16:9 and i have to manually set their aspect ratio -- can i just highlight all clips and do it just a few clicks or do i have to do it manually one clip at a time?

hello

My problem is it keeps freezing and than vista hav to close it down
doe anybody know what can help
Also if i save een projekt i can cut/edit it then is vreezes also
thanks

I am having the same problem and just submitted a request for tech support. What are the details of your problem? The program hangs for me when trying to convert a 9GB AVCHD file to MPG-2 DVD format. It finishes through the analyze step and then hangs when it starts the writing the file output. It works fine for smaller files. I'm running Vista with 4GB of memory and 500GB of free HD space. Intel Duo 2 Core process. The computeris more than up to the task ofsupporting this type of workload.

Will TMPGEnc 4.0 XPress compress a 1hr 40min video on to a single layer DVD?

Yes, there are bitrate settings that you can adjust upon selecting the DVD output template. You can select what type of media you have (in your case, single-layer DVD) and then set the percentage of the media capacity. TMPGEnc 4.0 XPress will automatically adjust the audio and video bitrate to fit your target percentage.

i had download and try the Tmpgenc 4 express but when i start the application and i click on get lisence it prompt me error that connection to the server is failed, but my internet connection is fine.

please help.....

thanks

What country do you live in? I know that some governments block certain communications. China and Singapore are some of the countries where this occurs.

coinitialize has not been called. (error code 0x800401F0)

I get this error when I try to encode with MPEG4.

I've tried tons of settings from default to playing with many things.
Always this error.

I can't find anything on this error and tmgenc 4.

Any ideas??
THanks,
